The current work aimed to study the normal values of some hematological and biochemical criteria of local quail and the effect of the breed, sex, and age on them. Two hundred quail (100 birds belong to each of white and light brown feathers local breeds), they were randomly distributed at 1st-day-age into 5 replicates, 20 birds/ replicate for each breed, and the study continued till the age 84 days. The results of the current study had revealed that the breed and the age, each alone did not significantly affect the physiological and biochemical parameters in this study, whereas the sex factor affects significantly most of the study parameters. The males were highly significant as compared to the females in the following parameter values: red blood cells count, hemoglobin concentration, packed cell volume, mean corpuscular hemoglobin concentration, monocytes%, basophils%, glucose, cholesterol, uric acid concentrations and aspartate aminotransferase activity. While the females were significantly higher to the males in mean corpuscular volume, lymphocytes%, triglycerides, total protein, globulin, and alanine aminotransferase activity. In conclusion, the sex of the bird alone and its interaction with breed and age had the greatest impact on the hematological traits.
